OnePlus has reportedly launched the OnePlus Watch Cobalt Limited Edition in China. This variant uses a cobalt alloy instead of stainless steel build, offering a sturdier frame. It also features a sapphire glass, but all other specifications are identical to the regular OnePlus Watch. The Cobalt Limited Edition has been priced at CNY 1,599 in China and is set to go on sale from May 17, but Indian pricing and availability are yet to be announced.
